Hi Franck,

fireModelChanged is an internal method - you should never need to invoke 
it. Basically, it is defined in the various model implementations - when 
you change data to the model (eg. adding data, removing data, etc), then 
the model notifies any listeners "hey, something has happened - better 
refresh yourselves"

So this method is an internal communication mechanism for models to talk 
to the components that use them.

THat help?

I which to implement TemplateModel, which means also implementing Model
and Contextual, but I cannot see fireModelChanged anywhere. However,
all AbstractxxxModel I see are providing a fireModelChanged() method.

I was just wondering what this is for, and why it's not defined in the
interfaces if mandatory.

Thanks,
